Final answer:
The electric company uses power and time to determine the cost of electrical energy for a business.
Step-by-step explanation:
The electric company uses two factors to determine how much a business will pay for electrical energy: power and time. The relationship between energy and power is given by the equation P = E/t, where P represents power, E represents energy, and t represents time. The electric company measures power in kilowatts (kW) and time in hours, and the product of power and time gives the amount of energy consumed. This energy consumption is then used to calculate the cost of electrical energy.
